Sonic Lost World - Modifying HHD scene format

A HHD file contains the values for stage lighting, and it has the role of SceneEffect.prm.xml files, seen in Sonic Unleashed/Generations.
Current version of the tool is in my tool repository, but I don't plan to continue cracking the format since Sajid has made a complete 010 Editor binary template for it already. You can pester him to obtain it: / sajidur78
I also discovered a value that shows the light field cubes in stage.
